This is not a STORY. Others might help you if you posted on the FWD/AWD forum.
If the noise is coming from the passenger side footwell, could it be the blower motor? There are dampner motors on both sides of the instrument cluster, but you shouldn't hear them.
When is the last time you changed the cabin filter? It could be clogged and causing the fan to run too long. The fan will run after engine turn off if the AC has been on, that is to help dry the evaporator and is normal.
